The inner section A of the sleeve, however, is made larger than the others. This arrangement secures at the same time strength and cheapness ot construction, although a larger number of threaded sections With rings at their joints may be employed. All the wearing-surfaces are ground true after being hardened.

Myinvention may be applied to any desired size of wheel, and ou the lighter Wheels the inttlairmediate ring of balls G may be dispensed Wit An oil-cup nut surrounding the nut L and screwed onto the sleeve may be employed, if desired, to retain the lubricant in the journal and to prevent dust or dirt from obtaining access to the bearing.

The combination, with the hub of a vehicle-Wheel, of a sleeve inserted therein, consisting of a series of threaded sections having grooved ends and rings of balls located in the grooves between the ends of the sections, which are arranged to be screwed up to compensate for wear, substantially as described.

2. The combination, with the hub of a Vehicle-wheel, of a sleeve inserted therein, consisting of a series of threaded sections having grooved ends and rings of balls located in the grooves between the ends of the sections, which are arranged to be screwed up to compensate for Wear, and a ring of balls at one or both ends of the sleeve, secured in place by an annular plate or ring, substantially as described.

3. The combination, with the hub of a vehicle-wheel, of a removable sleeve inserted therein and consisting of a series of threaded sections having rings of anti-friction balls interposed at their joints, substantially as described.

4. The combination, with the hub of a vehicle-Wheel, of a sleeve inserted therein, consisting of the threaded sections A, B, C, and D, having rings of anti-friction balls interposed at the joints between the sections, substantially as described.
